Default Brakes soft

04 suburban z71. Busted a wheel cylinder. Replaced bleed system thoroughly. Brakes get firm. But when you crank it they immediately feel soft and when brake pedal is pushed the power steering pump chatters. Someone mentioned hydroboost. I've never heard of it, but my question is does the power steering tie into the brakes some how. Only chatters when petal is pressed down.

That is correct your vehicle has a hydroboost system. Below is a link concerning bleeding.
